title: Transverse maxillary and mandibular growth during and after bionator therapy: study with metallic implants.
abstract: BACKGROUND
  This study evaluated posteroanterior cephalograms before and after treatment and long term follow-up of Class II division 1 patients treated with bionator.
  
  
  OBJECTIVE
  The objective was to demonstrate the transverse growth of maxilla and mandible during and after bionator therapy.
  
  
  METHODS
  Measurement of transverse dimensions between posterior maxillary and mandibular implants, as well as the distances between the buccal, gonial and antegonial points were recorded. Measurements were analyzed at three periods: T1 - before bionator therapy, T2 - after bionator therapy and T3 - 5.74 years after T2.
  
  
  RESULTS
  There was statistically significant transverse increase due to growth and/or treatment for all variables, except for the distance between the anterior maxillary implants.
  
  
  CONCLUSIONS
  During the study period only the anterior maxillary area did not show transverse growth.
